his invention relates to wire spoke lacing for wheels particularly wheels used for supporting or traction purposes in connection with tractors, trucks, bosses and other kinds 5 of automobiles; airplanes, bicycles and other vehicles.

My invention aims to provide a wire wheel wherein a novel arrangement of spokes affords a substantial support for a rim relative to a hub and resists side thrusts, so that the wheel structure is comparatively rigid, yet possesses that degree of resiliency found advantageous compared to wooden spoke wheels.

My invention further aims to provide a wheel of the above type wherein the wire spokes are tangentially disposed relative to the wheel hub in the plane of wheel rotation. The spokes are arranged in three conical formations with two of the formations intersecting, and the spokes are numerically distributed in these formations so that two of said formations will be the equivalent of the third formation. All the spoke forma tions cooperate in providing the trussed structure between a tire supporting rim and the hub of a wheel, so that lateral shifting of the rim relative to the hub is practically impossible under the stresses and strains incident to vehicular travel with heavy loads.

My invention further aims to provide a wire spoke wheel wherein the spokes are arranged in sets, with the spokes of each set of equal length. All of the spokes are disposed hub for supporting a rim, and there is a uniform angularity of the spokes assuring a rigid structnre.

My invention still further aims to provide rangement aflords a maximum clearance for a brake drum within the wheel structure, and it is by virtue of such clearance that a powerful. brake mechanism may be employed, especially a large and wide brake drum with a maximum braking surface.

My invention will be hereinafter specifical ly described and then claimed, and reference will now be had to the drawings, wherein Figure 1 is a side elevation of a portion of a wire spoke wheel in which the spoke ara wheel in accordance with this invention,

which are tangentially disposed relative to the hub 1 in the plane of wheel rotation. The

outer ends of all of the spokes are suitably connected to a tire supporting rim 8, and reference will now be had to said spokes.

. The series of spokes 5 have the inner. ends thereof anchored in the member 2 and said spokes extend outwardly and inwardly from hub 1 withthe outerend's the outer'end ofthe of said spokes anchored edge of the rim 8. This arrangement of spokes provides a slmilar formation,

which have the inner anchoring member the spokes sidering the spokes 2, the spokes mayb with the inner serie allel planes of the conical formation, and a is that of the spokes 6,

the arrangement of ends connected to the 3, while theouter ends of 6 are connected to the rim 8 contiguous to the inner e said to be in parallelism s of spokes 6 between par side edges of'the rim 8,

while the series of spokes 5 intersect the outer side plane of the rim 8 and end of the hub'l.

The series of spokes 7 are arranged the reverse of the spokes 6 extend to the outer and the inner ends of the spokes 7 'are connected to the anchoring member 4 and extendoutwardly to intersect the conical surface generated by the spokes 6, so that the outer ends connected to the rim 8,

edge thereof.

The number of of the spokes 7 may be adjacent the outer side spokes 7 is substantially equivalent to the combined number of spokes 5 and 6, so that the seriesof spokes 7 may resist as great an outward lateral pressure on the rim 8 as the lateral inward pressure exerted on the'combined spokes 5 and 6. Considering the spokes 5, 6 and 7 shown 1n Fig.

2, as a set, it will be noted that the angularity 5 type of wheel hub,

b ring m n and the {other series and the length are uniform. The spokes 7 cooperate with the spokes 6 in supporting the rim 8 relative to the hub l, and the two conical formations of these spokes afford an interlacing to provide a substantial fabricated structure between the rim and hub. Of course the outer series of spokes ,5 may ,cooperate with the spokes B -and 7 for resisting radial pressure, but the conical arrangement of the outer spokes 5 is to resist lateral stresses and strains, so-Itha-t the rim'i-8"is pos'itively tied to the hub without any danger of one shifting co-axially of the other.

It will also be noted that the distribution of the inner ends of the spokes'5, 6 and 7 is such ,asto provide a long -bearing on thehub 1, the length of the bearing being greater than-the width. of .the.rin1 .8,and it is in'this connection that the ri;m 8 cannot be tilted or otherwise hodilyshifted out ofits defined pgg tipnon plane of: rotation a a gh angle to the longitudinal axis of the ghubll gainjconsideringmhe spokes 6 7, 1t be'seen in Fig. 2 that there is a wide will Zandradial 'clearance 9 for .abrake drum 10 .mounted on the hub. It ,is thereforeposisibleto use a \wide obtainmaximum braking areaor surface for and large brake drum to ;a brake band.

I attach considerable importance to the conical formations of the spokes, and their specific arrangement between a wheel ,hub and rim, yet desire itto beunderstood that my invention isnotlimited to anyparticula-r What I claim is 1. In a wheel structure,,a'hub, a rim, and three series of spokesof equal length connecting said huband rim, two of said series of spokes beingvdisposed in parallel planes,

f spokes crossing that first named series which is nearer :said other .series at the hub, the crossing occurring at substantiallyzthe mid points of the spokes .of oneof said-series.

2. In a wheel structure, a.hub,,a rim, and three series of spokes connectingsaid 'hub and rim, two of said seriesof spokes being disposed in parallel planes, and the other series of spokes intersectingthe planeofone of the other series of spokes, the number of spokes in the :firsttwo mentioned series being approximate-to the number of spokes in the last mentioned series.

3. In a wheel structure, a hub, a-rim, a conical formation of spokes connecting the outer end of saidhub to the outer edge of said rim, a conical formation of spokes connecting an intermediate portion ofsaid'huh tothe inner edge of said rim, and .a conical formation of spokes connecting the inner end of said hub to t t r e ge o sa d rim, the n mberof p k in t l menti d formation b ng .forma ions, are
